DATA LIST / ACTIVE TEST

1. READ DATA LIST

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Engine and ECT / Data List.

(g) According to the display on the Techstream, read the Data List.

2. PERFORM ACTIVE TEST

HINT:

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Engine and ECT / Active Test.

(g) According to the display on the Techstream, perform the Active Test.

Engine and ECT

Tester Display	Test Part	Control Range	Diagnostic Note
Activate the Solenoid (SLU)	Operate shift solenoid SLU	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.
Activate the Solenoid (SLT)*	Operate shift solenoid SLT and raise line pressure	ON or OFF HINT: OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands SLT solenoid to turn OFF) ON: No action (normal operation)	[Vehicle Condition] Vehicle stopped. Engine idling.
Activate the Solenoid (S1)	Operate shift solenoid S1	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.
Activate the Solenoid (S2)	Operate shift solenoid S2	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.
Activate the Lock Up	Control shift solenoid SLU to set automatic transmission to lock-up	ON or OFF	Possible to check shift solenoid valve SLU operation. [Vehicle Condition] Throttle valve opening angle: Less than 35%. Vehicle speed: 80 km/h (50 mph) or more.
Control the Shift Position	Operate shift solenoid valve and set each shift position	Press "→" button: Shift up Press "←" button: Shift down	Possible to check operation of the shift solenoid valves. [Vehicle Condition] 50 km/h (31 mph) or less.
Activate the Solenoid (SR)	Operate shift solenoid SR	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.
Activate the Solenoid (SL1)	Operate shift solenoid SL1	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.
Activate the Solenoid (SL2)	Operate shift solenoid SL2	ON or OFF	[Vehicle Condition] Engine stopped. Shift lever in P or N.

HINT:

*: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the Hydraulic Test (See page ) as well. Note
that the pressure values in the Active Test and Hydraulic Test are different.
